wATER-'i-'ILTEE- SPEIFICATION forming part of Letters Patent No.637,095, dated November 14, 189. Application led May 81,1899. Serial No.7183828. (No mod-el.)

To dll whom it may concern:

Be it known that I, EMIL T. DREIEE, of Hanapepe, Kauai, Hawaii, haveinvented a new and Improved Water-Filter, of which the following is afull, clear, and exact description.

My invention relates to an improvement in water-filters designedparticularly for household use, although capable of other use; and itconsists of the novel features which will be hereinafter described andclaimed.

Reference is to be had to the accompanying which projects from the lowerhead C of the cylinder or casing A. This lower head is secured to thecasing A by having a threaded flange C' screwing upon the lower end ofthe casing, and the upper end of the casing is closed by a screw-head B,which is secured to the casing in a similar manner.

At the center of the upper head is a projecting boss b, which has a holepassing through the same and threaded to receive the watersupply pipe I,provided with a valve J, by means of which the iow of water through thefilter may be regulated.

The cylinder G, besides having the longitudinalbore mentioned,hasanumber of small boresor passages g, extending from said central bore tothe exterior of the cylinder. These are filled with a brous filteringmaterial, as sponge, which permits the water to reach the central carbonstick H more readily than would be possible through the body of thecylinder G, and yet filters 'and delays the water somewhat. Within thecentral bore is placed a stick H of carbon or similar ltering material.The cylinder G is suliiciently smaller than the casing A to leave awater-passage about the cylinder.

The headvC is provided with a central boss C3, which has a centralpassage communicat- This cylinder at its lower' end or base screws intoa circular ange C2,

ing with the end ofthe carbon stick ri and threaded exteriorly toreceive the threaded collar d of the chamber D. This chamber D is hereinshown as being of spherical shape and is illed with sand K. Within itslower end is screwed a plug E, which is provided wit-h a central bore orpassage, through which the Water escapes from the ilter. This plugextends some distance within the sand-receiving chamber D and has theinner extension E' thereof provided with perforations, forming, ineiect, a sieve to permit the escape of the water while retaining thesand. This plug is also provided with a valve F, by means of which theiiow of water may be controlled.

The operation of the device is as follows l The upper end of the casingA is connected with any suitable-source for water, as a faucet I. W'ateris admitted betweenthe casing A and the cylinder G and obtains access tothe central filtering-stick H through the holes g, which are iilled witha fibrous material, as sponge. Water after filtering through the carbonstick H enters the sand-chamber K, where it is further iltered, beingdischarged through the valve E.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patentl. Aiilter, comprisinga casing havingawater-supply connection thereto, a cylinder extending within saidcasing and having a longitudinal bore therein,and exteriorly connectingpassages extending outwardly from said bore, and a carbonfiltering-stick in said bore, the casing having a discharge-passagecommunicating with one end of the carbon stick, substantially asdescribed.

2. A filter, comprising a casing havingawater-supply connectiontherewith, a removable cap having a discharge connection therewith, acylinder adapted to be secured to the said cap within the casing andhaving a central bore, and openings communicating from said bore totheexterior of the cylinder, said cylinder being smaller than the casing toprovide a water-space between them, a carbon stick filling the bore ofthe cylinder, and a water discharge communicating with said bore,substantially as described.
